Issue Identification
Issue # Issue Title Issue Description Related Work Responsible Forum
1 Accommodate E.164 Number Portability

(Related to Issue 14)
This issues relates to the three types of portability;

- Service Provider
- Location
- Service
- ITU Number Portability Supplement
- Q.769.1
- ENUM
- SIP
- DNSEXT
- ETSI TIPHON
- SG2(WP1/2)
- SGs 11, and 16
IETF-ITU
2 Transfer of Caller and Called Party information The transfer of Caller and Called Party involves only one layer. Transfer of Caller and Called Party information between both parties - ETSI STF 157
- SIP
- H.323
- H.248
- MEGACO
- SIGTRAN
- SG2(WP1/2)
- SGs 11, 13 and 16

3 E.164 Number for IP based End-User The allocation of E.164 resources to IP based users - H.323

- SGs 11, and 16

4 E.164-DNS Interworking

(Related to Issue 8)
Collaboration on the identification of specific issues and appropriate work parameters related to E.164 – DNS interworking (such as Interworking concepts and principles, Administrative and operational aspects, Identification of other relevant aspects.) - DNSEXT
- ENUM
- 3GPP
- 3GPP2
- SG2(WP1/2)
- SGs 4, 11, and 16
IETF-ITU
5 Carrier Selection/Preselection Originating networks often have to support ability of customer to decide, e.g., "send all my international calls via operator X." As such, where the originator is IP-based, the "E.164-IP Resolution Process" will have to determine a result, e.g., egress gateway based on the combination of destination E.164 number and user preference/CLI, i.e., the answer may vary according to context and there may be no universal answer for a given E.164 number. - ITU Supplement on Carrier Selection

- SG2(WP1/2)
ITU Lead and IEFT-ITU
6 E.164, URL’s and "Telephony" Wide range of E.164 "telephony" issues raised in Internet drafts proposing URLs, e.g.,

- Tel/fax/modem
- Global/local
- Dialling & post dialling
- Options & features; and
meta-issue of process (individual’s drafts vs. those associated with Working Groups).
Internet drafts such as

- afifi-sixtel-00.txt
- antti-telephony-url-12.txt
- kurrasch-tmar-00.txt
- gelman-phone2web-00.txt

Internet drafts such as those related to "VPIM" and to IETF working groups
IETF
7 E.212 – IMSIs & mobility with IP In IETF documents, IMSI’s are mentioned but ITU-T Rec E.212 is not often referenced. A review of the IETF documents is needed to ensure that the appropriate use of the term IMSI is used. Rec. E.212
Rec. E.214

8 Administration of E.164 numbers in domain name servers

(Related to Issue 4)
How are numbers distributed among domain name servers in different situations? An example, a DNS rule is one authoritative server per telephone number. What if two SPs wish to list information on a telephone number? ENUM IETF
9 How changes get propagated throughout the proposed ENUM DNS service One example, if an Area Code changed – propagation must be timely (within expected range). ENUM requirements related work IETF
10 DNS/ENUM Service logic How does DNS/ENUM resolve whether service logic is needed, e.g., via TRIP protocol, for a particular E.164 name lookup?

What is the response to a user if service logic is needed (DNS/ENUM protocol issue)?

14 Interworking of routing addresses and IP names/addresses

(Related to Issue 1)
ITU are defining an "international" routing address plan, e.g., for use in the portability of [global] E.164 numbers, and routing of calls to potential regional country codes (ETNS). There may be a need to interwork routing addresses with IP Technologies. E.353

Documented Definitions (Source: Recommendation E.191)
Name ("Naming") – a combination of alpha, numeric and symbols that is used to identify end users.

Address ("Addressing") – a string or combination of digits and symbols which identifies the specific termination points of a connection and is used for routing (functions as a "locator").

Number ("Numbering") – a string of decimal digits that can function both/either as a Name and/or an Address. Portability reduces a Number’s role as an address and Numbers are increasingly functioning solely as a name.

End User - a logical concept which may refer to a person, a persona (e.g. work, home), a piece of equipment (e.g. NTE, phone), an interface, a service (e.g. Freephone), an application (e.g. Video on Demand), or a location.
